The resulting CSV file uses semicolons as separator, has quoted (with double quotes) string fields, and is UTF-8 encoded. You can open it in any text editor or in your favourite spreadsheet application on any system. The raw file looks like this:

Import into Google Sheets

When importing a CSV file from ArtHandler into Google Sheets, please select Custom as Separator Character and enter a semicolon ; as custom separator character.

Import into Microsoft Excel

The exported dataset is encoded in UTF-8. While UTF-8 is the standard for multilingual character encodings, it is not correctly interpreted by Microsoft Excel on a Mac. Users of Excel that have non-latin characters or Emojis in any field of their ArtHandler database must convert the UTF-8 to UTF-16 so the file can be imported correctly.
